With the above and other objects view,

as will be hereinafter apparent, the invene t1on consists 111 general ofcertain novel features of construction and combinations of partshereinafter fully described, illustrated in the accompanying drawings,and specifi+ cally claimed;

In the accompanyin drawings like characters of reference indlcate likeparts in the several views, and :.Figure 1 is a side view of theimproved thill tug, the locking memher being shown closed in full linesand open in dotted lines. Fig. 2 is. asection on. the line 2-2of Fig. 1with the locking member open. Fig. 3 1s a SGCtlOIllOf the device on theline 33 of Fig. 2, and Fig. 4: is a detail View of the preferred lockingmember. Fig.

5 is a detail view of a modified locking member.

At the rear, above the flanges the body is reduced as at 17 to receivethe cars 18 of an extensionmember 19 secured behind the rear: legof thebody by arivet 20 or the like. i This extension member is rebent at itsupper: end to form a loop 21 wherein is held a loop 22 by means ofiwhichthe device is attached to the stops connectedwith the saddle of aharness.

The ears18 are connected by a bar 25 and pivotally mounted on this baris a curved plate 26provided adjacent its lateral edges withrebentextensions 27 forming eyes surrounding the bar 25 adjacent eachear 18.:

Around the bar 25, between the extensions 27 is coiled a wire 28 havingextended ends 291 one whereof bears against the body 10 and the otheragainst the late 26 so that the latter is constantly urgec to openposition, .both

Wire and plate being of spring metal.

The outer or free end of the plate 26 is 1 provided with a .rebentextremity 30 arrangedto be sprung over and lock on the bar 16 whe n thedevicenis closed and this end is provided with an outturned lip 30 tofacilitate its disengagement from the bar16. In the modified form shown:in Fig. 4 this lip is omitted.

Each 1e of the Unshaped body portion is provide near its upperend with ahole 31 through which. extends a rivet 32; for

securing ;a leather strip or buffer 33 which rests partly Within therecess 11, and extends 1 beyond: the inner surface of the bodyporw tion10, as shown.

In the operation of thisdevice the thills kind describedandfor thepurpose specified. It is obvious that many minor changes may be made inthe form and constructlon 0f the device herein described andillustrated.i It is not therefore desired to confine the inventionto'the exact for h herein set forth but it is ished to include all suchas come Within the scope claimed.

Having thus" described thev invention, What is claimed as new, is

1. Ina thill tug, a U shaped body portion, ears formed on one leg of theU, a rod connectingsaid ears, a resilient plate having one. end bentaround said rod as a pivot, a spiral spring surroundingsaidrod andtending to hold said plate in its opQn position,downwardlyandinwardlyturned loops upon the free end of said resilientlate,'ears formed upon the other leg of sand U shaped body loops on saidresilient plate.-
